@RATE FOR FIREQPLACES.

SPECIFICATION forming part of lLettera Patent No. 342,115, dated May 18, 1886.

Application filed June 12, 1885.

To all whom it may concern:

Be it known that I, CnARLns C. MoGLosKEY, Jr., a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Grates for Fire-Places; and I do declare the following to be a full, clear, and exact description oi' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reierenee being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My present invention relates to improvements in grates for fire-places; and it consists in the general arrangement of parts as hereinafter set forth, and pointed out in the claims.

The object of my invention is to construct a cheap and durable grate, one that may be readily taken apart for repairs Without interfering with the brick-work or any of the permanent ixtures of a lire-place.

In the drawings foriningapart of this specification, Figure l is an isonietrieal View having a portion of the hood broken away to show the gear-wheels of grate-bars. Fig. 2 is an isometrieal view of thei'rame, showing manner ol' inserting the grate-bars. Fig. 3 is a crossseetion in elevation of Fig. 1. Fig. 4 is an enlarged section of a grate-bar. Fig. 5 is a rear View of the grate front and hood having parts broken away. Figs. 6 and 7 are enlarged details.

The frame consists of the parts a a n? u a a and legs Z', which are cast in one piece, all of which are old. The front a of the frame is provided with a series of slots or grate-bar bearings, e. (See Fig. 2.) The grate-bars g (in crosssection) are of the form of an equilateral triangle, the faces being slightly coneaved. `(See Fig. 4.) The edges of thebars are cnt ont at i, the intervals forming clinker rakers or projections c. The rear ends of the grate bars are provided with journals s, which have a bearing in the holes d of the plate a. (See Figs. 2 and 3.) The front ends of the grate-bars are provided with journals h, which lie in the slots e of the front plate. The outer ends of said journals diverge `from a round toan eqnilateral trian- Seriul No. 168,455. (No model.)

gular form, (in eross-section,) as shown at n of Fig. 2. Fitted loosely onto said ends is a series of gear wheels, e, having equilateral triangular holes o through them. Said gear- Wheels engage with each other, as shown in Fig. l. rlhe central bar is provided with the arm o, to which the crank-handle H is applied to revolve said grate-bar, as in removing the refuse from the burning fuel.

The grate-front consists of the horizontal bars D D, united by the vertical barst, in which the dark lines indicate openings. (See Fig. 1.) B is a hood,joined. at the ends by the horizontal arms S, which extend outward at right angles to the vertical bars t, joining the end harsen. (See Figs. l and 5.) Said hood along the front is insulated from the bar D, as shown by dark shading h2 of Fig. l.

It will be observed that when the grate-front is in position the hood B passes over the series of wheels z, and by said hood the-wheels are prevented from working ofi" the lends of the grate-bars g, (see Figs. l and 3,.) and by forming the opening h2 along the front I obtain an air-passage between said hood and the grate-front, whereby if the hood be nickle plated it may retain its lnsterwitliout coloring by heat, as would be the case without the airpassage to keep the hood cool. I attach to the frame the vertical fronts A A by means of gage with the prong r upon the extension as. The fronts A A are provided with a flange, b, having holeszvw. (See Fig. 2.) The end bars, m, of the grate-front have corresponding holes, t" i', (see Figs. l and 5,) and by bolts passing through said holes the grate-front is secured in position, as shown in Fig. l.

The bar D of the grate-front is provided with a series of depending lugs, fl. (See Fig. 5.) Said lugs (when the grate-front is in position) pass within the slots e of the bar a, their ends fitting upon the journals 7i of the gratebars, (see Fig. 8,) thereby preventing said C represents the common draft-front, having knob 7c, for operating the draft-slide.

The side extensions, a3, are provided with a series oi' holes along theinner edge. The lirebricks are laid-upon said extensions, and when building a wide tire-pot the bricks are placed grate-bars from lifting as they are revolved.

a bolt passing through the holes c3, which en- IOO back from the series of holes, when said holes will allow the ashes accumulating to fall through, thus preventing the burning out of the frame.

I place upon the rear bar of the frame the perforated plate B', which strengthens the frame and elevates the back, the ire-brick being placed along its upper edge. The slot f of the hood receives the arm o of the central grate-bar. (See Fig. l.)

It willbe observed from the foregoing construction should a grate-bar burn out or become broken it may be readily taken out by removing the bolts attaching the grate-front to the uprights A A, when the front and hood may be readily taken out, as shown in Figs. 2 and 5, when the grate-bars, wanting repair, :may be raised at the front out of the slot or slots e, as shown in Fig. 2, when, drawing forward, the grate-bar will be removed. The wheel z maybe taken oli" and placed upon the new grate-bar to be insert-ed, which is aecomplished by placing the journal s of the gratebar in one of the holes d of the frame and dropping the journal h into the slot e. The grate-front being then replaced, the work is done.

Having thus fully set forth my present invention, what I claim as new, and desire to 3o secure by Letters Patent, is-

l. In a grate for lire-places, the combination of the supporting-frame, the series of revolving grate-bars, the uprights bolted to said frame, the open grate-front having the hood formed integral with said front, the series of gear-wheels detachably mounted on said grate-bars and housed within said hood, as and for the purposes specified.

2. In a grate for replaces, the combination of the frame, the series of revolving grate-bars journaled thereon, the vertical uprights A A, the open grate-front, its hood B, formed integrally therewith, being insulated from said front, the series of gear-wheels mounted on said grate-bars and housed Within said hood, as and for the purposes set forth.

3. In a grate for fire-places, the combination of the frame consisting of the parts aa a2 a a3 a3, formed integral of a series of grate-bars pivoted within said frame, the uprights attaehed thereto, of the open grate-front, its hood attached thereto by the arms S, the series ot' lugs d', adapted to pass within the series of slots e of the bar a, and series ofgearwheels housed within the hood, substantially as specified.

In testimony whereof I afl-ix my signature in presence of two witnesses.
